what is hcg

HCG injection in follicular study is one of the crucial steps in predicting ovulation. hCG (Human Chorionic Gonadotropin) is a hormone that the placenta produces during pregnancy.

The hCG hormones signal the body to stop the menstruation process, and they also help thicken the uterine lining in order to support the growing baby.

The hCG levels increase and stay elevated for up to 10 or more weeks of pregnancy. Let’s learn about the significant role of hCG injection in follicular study.

Human chorionic gonadotropin (hCG) injections are hormone injections that have the tendency to raise a person’s chances of getting pregnant.
